Wind noise on internal microphone

Hi Roger,
In FM with OpenMDUV380 firmware the wind noise is also present, but not as disturbing as in DMR !

Hi Roger,

Is the noise present with the official firmware ?

Checked with GD77 and RT3S in both directions in FM.
GD77 (FM Mic: 1db, DMR Mic: 0db) <=> RT3S ((FM Mic: 0db, DMR Mic: 0db)

PTT on one device, receiving side on the other, holding the loudspeaker to my ear, I hear a distant roaring,
like when we held a large sea shell to our ear as children, because we were told 'listen, you can hear the sea roaring there'.

However, when I hold the devices in my hand at a reasonable distance, there is nothing to hear.

OK. No rush.

I was just trying to find out if this is a problem with our firmware, or whether its specfic to your radio hardware.

I always try to fix serious bugs as soon as possible

I tested on my RT3S ( Nov 17 2022 ) and I didn't notice any noise with internal microphone & antenna.

Do you hear some noise from the 9990 parrot ?

Original firmware restore RT3s:
After restoring the flash, the original firmware worked again!
I took this firmware-link (RT3s non GPS):
https://www.retevis.com/rt3s-dual-band- ... are-S19.06\ -> RT3s(CSV)-V19.06.bin

After extensive testing, I found that the wind noise is still there

OK.

Perhaps you can complain to the vendor that the radio is faulty

Hi Roger,
I found the error (wind noise in TX). It was the micro. It is extremely small...
